📚 Radians ↔ Gradians Conversion Details

Radians to Gradians Formula

gradians = radians × (200 / π)

To convert radians to gradians, multiply radians by 200/π (approximately 63.662).

Gradians to Radians Formula

radians = gradians × (π / 200)

To convert gradians to radians, multiply gradians by π/200 (approximately 0.015708).

Bidirectional Conversion

This converter works both ways simultaneously:

  • Type in radians → gradians updates automatically
  • Type in gradians → radians updates automatically
  • No buttons to click - works as you type

Common Uses

  • Mathematics and trigonometry
  • Engineering calculations
  • Surveying and navigation
  • Computer graphics and game development

📏 How This Converter Works

This is a bidirectional converter that works in real-time:

  1. Radians → Gradians: When you type in the radians field, the gradians field automatically updates
  2. Gradians → Radians: When you type in the gradians field, the radians field automatically updates
  3. No swapping needed: Both conversions happen simultaneously
  4. Real-time: Updates happen as you type, no button clicks required
// Bidirectional Conversion Logic:
gradians = radians × (200 / π)
radians = gradians × (π / 200)

// Example 1: Type "π" in radians (3.1416)
gradians = 3.1416 × (200 / 3.1416) = 200

// Example 2: Type "100" in gradians
radians = 100 × (3.1416 / 200) = 1.5708 (π/2)

📊 Conversion Table

3π/2 (4.7124) 300 270°
2π (6.2832) 400 360°
π/4 (0.7854) 50 45°

❓ Frequently Asked Questions

Q: What is the relationship between radians and gradians?

A: A full circle is 2π radians (approximately 6.2832 rad) and 400 gradians. Therefore, π radians = 200 gradians.

Q: How does the bidirectional conversion work?

A: Both input fields work simultaneously. When you change the radians value, gradians updates automatically. When you change the gradians value, radians updates automatically. No swap button needed.

Q: Do I need to click any button to convert?

A: No! The conversion happens automatically as you type in either field.

Q: What is a gradian (gon)?

A: A gradian is a unit of angle measurement where a right angle is 100 gradians and a full circle is 400 gradians. It's also called a "gon" or "grade".
